ABSTRACT: This paper presents a simplified routing wire for anti-parallel configuration. This scheme is applied to parallel feedings to a circular polarization 16-antenna array. The unit antenna is composed of three elements of feed and reactance elements, and ground plate. Then, a configuration of 16-antenna array is presented. A 4- antenna array composed of smoothed routing wire is set at each quadrant. The directions of each 4-antenna array at the first and the second quadrants are parallel, and anti-parallel at the third and the fourth quadrants. A grounded circular cylinder is set at the peripheral of 16-antenna array. The characteristics of the proposed antenna array are obtained by 3D computer simulation. It was found that this scheme is applicable to wideband and practical systems.
KEYWORDS: Circular polarization, plane array antenna, parallel feeding, anti-parallel arrangement, simplified routing wire.
